CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application Ser. No. 60/659,235 filed on Mar. 7, 2005, incorporated herein by reference.

FIELD OF THE INVENTION

This invention is drawn to the field of structures and laminations, and more particularly, to novel modular clean room structures and laminations for the life sciences and health-care and other industries.

BACKGROUND OF THE INVENTION

The primary function of the Life Science Clean Room Wall Manufacturer is to create “aseptic” conditions throughout—systems that, by design, are easy to sterilize and will prevent microbial contamination. This is the FDA requirement known as “cGMP,” which stands for current Good Manufacturing Practices. The FDA informally looks to U.S. Pat. No. 797 as the latest mandate for facility protocol in the life sciences. According to 797, all pharmacies, health care institutions and facilities where compounded sterile preparations are prepared stored and dispensed, are to adhere to even higher standards of aseptic protocol. For such products as “biologics, diagnostics, drugs, nutrients or radiopharmaceuticals, and such preparations as baths and soaks for live organs and tissues, implants, inhalations, injections, irrigations, metered sprays, ophthalmic and optic procedures,” raising the standards of cGMP is the FDA's charge.

To adhere to these requirements, wall manufacturers must construct and finish interior surfaces that are homogenous, monolithic, and free of seams, joints and open crevices that harbor bacteria. Typically, walls heretofore have employed mitered corner posts, surface applied corner moldings, hand-formed plastic radius or on-site thermo-formed corners.

Most often, end users find themselves spending exorbitant amounts of money on excessive labor and materials costs to custom build these conditions. And, once achieved, end users still find themselves with a continuous problem—the inability to deconstruct or demount the wall system in a way that will prohibit contamination and reconstruction.

In most cases, if not all, significant portions of wall systems are destroyed during retro-fit procedures, whether it's demounting or expanding.

There is thus the need provide modular clean room structures and eliminations for the life sciences health care and other industries or applications that overcomes these and other disadvantages.

DETAILED DESCRIPTION

The modular clean room structures for biological sciences and other applications of the present invention enable to provide clean rooms that are modular in design, so that they may be installed, taken down and re-installed as the needs of the situations change, and also enable to provide clean room walls that are easily wipeable to prevent microbe buildup and/or contamination at the corners, floors and ceilings. The modular clean room structures for biological sciences applications of the present invention may be able to support loads or may be non-load bearing. The modules are fastenable to load bearing or non-load bearing structures using seperable fasteners. There are seven principal modular clean room structures in accord with the present invention, namely, a base track, a ceiling track, inside and outside corners, and connector wall sections of preferably two lengths, a larger and a smaller wall connector, as well as a two-piece batten wall connector. The sixth principal component is the preferably laminated, partition wall members themselves. Joints for the base and ceiling tracks are the seventh. Another component is a window frame module. A further component of the modular clean room structures in accord with the present invention is an end cap panel. The base track and the ceiling track have coved surfaces that are easily wipeable. The inside and/or the outside corner subassemblies have coved surfaces that meet with the coved surfaces of the base track and of the ceiling track to provide easily wipeable floor-to-wall, wall-to-ceiling and wall-to-wall surfaces at the interfaces therebetween. The inside and outside corner subassemblies are preferably vacuum-formed and enable to clad-over the corners of rooms and the corners of T-walls. The corner and T-wall subassemblies provide chases in which load bearing members may be used to provide load bearing struts and/or utility wire runs. The wall subassemblies are lightweight laminated structures having a core and skins and the base track and ceiling track subassemblies are preferably extruded. The modules are typically fabricated of standard-sized components and enable to provide rooms having easily wipeable surfaces of any given size in dependence on the number and arrangement of components utilized.

With reference to FIG. 1, the principal structures that may be fabricated in accord with the present invention and joined to provide inside and outside load bearing and non-load bearing clean room environments for the biological or other industries will now be described. As shown in FIG. 1, generally designated at 100 is a schematic plan view illustrating a corner subassembly generally designated 300, a T-wall subassembly generally designated 500 and a wall subassembly generally designated 700. Preferably laminated, partition walls 150 to be described are joined at corners by the corner subassembly 300 that includes insides corner subassembly 350 and outside corner subassembly 400. The preferably laminated, partition walls 150 may also be joined in the manner of a T-wall 500 by inside corners 350 and T-wall member 550 to be described and may be joined by wall sections 700 using wall members 750 to be described.

Referring now to FIGS. 2 and 3, generally designated at 50 is the base track in accord with the present invention. The base track 50 is used to provide a seamless transition between the floor and the wall panels to be described that are easily wipeable and minimize microbe contamination. The floor track 50 is of standard length, such as 12 feet, and extruded of polyvinyl chloride or other material capable of repeated wiping and able to withstand multiple doses of strong cleaning agents. The base track 50 includes concave sidewalls 52, a top tongue 54, and bottom radius edges 56 that accept caulking. A cross brace 58 provides strength to the base track 50 and divides its hollow interior into upper and lower cavities which may be employed as races for utility wiring or the like. As will be readily appreciated, the concave surfaces 52 provide coves that are easily wipeable. The tongue 54 mates with a groove of a joint member to be described to provide a demountable interface between the base track and the laminated wall panels.

Referring now to FIGS. 4 and 5, generally designated at 100 is a joining member in accord with the present invention. The joining member 100 is used to attach the base track to the laminated walls at their bottom and to attach the ceiling track to be described to the laminated walls at their top in a manner to be described. The attachment between the laminated walls and base and ceiling tracks may be non-progressive or progressive. The joining number 100 is of standard length, such as 12 ft., and extruded of polyvinyl chloride or other material. The joining member 100 includes a U-shaped member 102, flanges generally designated 104 and grooves generally designated 106 provided along the flange's outer faces. As appears more fully below, the U-shaped member 102 provides a groove that accepts the tongue 54 of the base track 50 (FIGS. 1 and 2) and defines a tongue for the ceiling track in a manner to be described. When laying the base track for non-progressive installations, the groove provided by the U-shaped wall 102 accepts the tongue of the base track and prevents delamination of the laminated sidewalls, not shown. The U-shaped member 102 absorbs wear and tear and provides for repeated re-use of the laminated walls.

Referring now to FIG. 6, generally designated at 150 is a preferably laminated, partition wall panel in accord with the present invention. The laminated panels 150 are preferably of standard length, such as 4 foot by 8 foot panels that are 2 in. thick. Any suitable core material, such as aluminum honeycomb, and foam, and any suitable skins 154, 156, such as of plastic, polyvinyl chloride, or other veneers, may be employed. The laminated panels 150 are provided with a longitudinal cutout 158 along their bottom edges that is adapted to receive the joint 100 (FIGS. 4, 5). As described above, the joint placed into the bottom groove receives the tongue and prevents the laminated panel 150 from delaminating with repeated use.

FIG. 7 is an end isometric view illustrating the base track joint member 100 set in the laminated wall panel. The inset 100 preferably is adhesively bonded into the cut-out provided at the bottom of the laminated panel 150. Partition walls of another structure or fabrication technique may of course be employed.

Generally designated 200 in FIG. 8A is the ceiling track in accord with the present invention. The ceiling track 200 includes an enlarged top member 202 whose sidewalls taper downwardly to provide concave wipeable surfaces 204 at the laminated wall to ceiling interfaces. The concave surfaces 204, or coves, are easily wipeable. A strut 206 provides strength. The strut 206 divides the cavity of the ceiling track 200 to provide utility or other raceways. As for the bottom track, the ceiling track 200 is extruded to standard length, preferably 12 ft., and is fabricated of polyvinyl chloride. The ceiling track 200 is separably attached to the laminated panels 150 by means of the joint 100 as shown in FIG. 8B. The joint 100 in the case of the ceiling track serves as a tongue that mounts in the open mouth generally designated 208 of the ceiling track 206 for progressive installations. The bead line, not show, again accepts caulking to provide a seamless ceiling track to laminated wall interface.

Generally designated at 350 in FIG. 9 is the vacuum-formed inside corner subassembly of the present invention. The inside corner subassembly 350 preferably is vacuum formed of a thermoformable material such as PVC to include an upstanding portion 352 having a C-shape defining an inside corner that terminates in a base 354 that is contoured to match the contours of the concave walls of the base track and the contour of the upstanding C-shaped wall 352. Ridges along the sides of the upstanding member 352 designated generally at 356 are provided for seamless interfacing with laterally adjacent panels at the corner subassembly 300 and/or T-wall subassembly 500 (FIG. 1). The ridges provide joggles in the vacuum-formed monolithic component which helps to rigidify it. The vacuum-formed inside corner subassembly 350 by means of the curvature of the portion 352 and the compound curvature of the portion 354 provides an aseptic condition. The inside corner subassembly may be removably joined by means of separable fasteners, not shown, to the laterally adjacent walls, or heat-welded thereto for progressive installations.

The window frame subassembly includes frame members 800, 840 having sashes 810, 850 and mounting flanges 820, 860 that surround glazing member receiving apertures generally designated 830, 870. Separable fasteners, not shown, are preferably employed between the mounting flanges 820, 860 and the confronting surfaces of the partition wall, not shown, to mount the frame members 800, 840 to opposing surfaces of the partition wall, which capture a glazing member subassembly generally designated 900 (FIG. 18) between the window sashes 810, 850 thereof. The separable fasteners provide an emergency release hatch function. Alternately, one or both of the frame member's mounting flanges may be bonded to the confronting surfaces of the apertured partition wall. The frame members 800, 840 are fabricated by vacuum forming any suitable thermoplastic material capable of repeated wiping and able to withstand multiple doses of strong cleaning agents such as PVC. The glazing member subassembly 900 may be of any size or shape and may be, for example, one fourth inch thick tempered glass or Plexiglas or other transparent material.

Referring now to FIG. 19, generally designated at 950 is an end cap panel subassembly of the modular clean room structures in accord with the present invention.

Ridges along the sides of the outstanding member 1152 designated generally at 1156 provide seamless interfacing with laterally adjacent wall liner panel laminations (or other structures) in accord with the present invention. A triangular-shape top wall 1158 is provided to close off the wedge that otherwise would be defined at the inside corner of the wall to be clad. The vacuum-formed inside corner subassembly 1150 by means of the curvature of the portion 1152 and the compound curvature of the portion 1154 provides an aseptic condition. A flange 1160 helps provide rigidity. The inside corner subassembly may be removably joined by means of separable fasteners, not shown, to laterally adjacent laminations (or other structures) or heat-welded or otherwise bonded thereto.

Generally designated at 1200 in FIG. 24 is the vacuum-formed outside corner wainscot lamination of the present invention. The outside corner wainscot lamination 1200 preferably is vacuum formed of a thermoformable material such as rigid PVC to include an upstanding portion 1202 having a rounded bull nose outside corner edge that terminates in a base 1204 having a concave cove that is contoured to match the contours of the concave walls of the wall liner panel lamination and of the base track subassembly described hereinabove and the contour of the rounded bull nose outside corner edge of the upstanding wall 1202. Ridges along the sides of the outstanding member 1202 designated generally at 1206 provide seamless interfacing with laterally adjacent wall liner panel laminations (or other structures) in accord with the present invention. The joggle of the ridges imparts rigidity. An inwardly extending generally horizontal flange 1208 along the base 1204 helps to provide the outside corner wainscot panel lamination 1200 with rigidity. The vacuum-formed outside corner subassembly 1200 by means of the curvature of the portion 1202 and the compound curvature of the portion 1204 provides an aseptic condition. The outside corner subassembly may be removably joined by means of separable fasteners, not shown, to laterally adjacent laminations (or other structures) or heat-welded or otherwise bonded thereto.

Referring now to FIG. 25, generally designated at 1250 is the liner wainscot panel lamination in accord with the present invention. Preferably, it is fabricated by vacuum forming, preferably 20 in. or 40 in. wainscot sizes corresponding to that of the inside and outside wainscot corner laminations described above. Of course, any suitable wainscot size for the liner wainscot panel and inside and outside wainscot corner panel laminations may be employed. The wall liner wainscot panel lamination 1250 includes a generally planar upstanding wall-covering portion 1252 that terminates in a coved foot or base 1254 whose curvature matches that of the other laminations or structures herein described so that it is usable therewith while being easily wipeable. The top edge is radiused as shown at 1256 to provide for ease of wipeability.
